ly' in section and partly in elevation, show with a suitable frame 14 of strip iron or angle 7 i frame 14 to which they are riveted. Each of V the supporting bars 7 is provided with a number of pressed-up. or looped members 22 forming eyes through which the lower ends of the respective springs 23 extend. Preferably there are two pressed up portions or eyes 22 for each spring 25, whereby the springs are properly supported and connected to the support'at one end. The upper ends of the springs are connected by suitable links and suitable springs 26 are also provided for standing flange- 30' having apertures for receiving suitable rivets 31. I The seat section 13 is provided with a frame 32 which may be of angle bars '01 strip iron, as desired, and is preferably substantially rectangular.

This frame carries a suitable resilient bottom'33, said'bottom being preferably formed with links held in place by suitable springs 34. Connected to the frame 32 are thearms '6 and 7 Each of the arms is provided with upstanding spindles 35 riveted or otherwise secured to a bar 36 having a rear section 37, as shown in Figure 2. The end of the rea-r section '37 -is riveted or otherwise'secured to frame 32 so that when the runner 5 is placed on member 36, the arm is complete. In'o'rder to brace the arms 6and7, suitable bracing members 38 and 39 are provided.

As these bracing members are identical,th-e description of one will apply to both. In FigurelO bracing member 38 is shownland with it part of the angle bar 39 which "forms a rear panel of the arm. Suitable rivets 40 secure the brace 38 to'the frame '13 and to Inember'35.

The end'piece' 10 is rigidly secured to hinge members '41, said hinge members being hingedly connected with'fraine 32, so that end member 10 may be folded against the frame '32. whenever desired. The samearrangement is provided forth'e'end member 11 asthese members are designed to befolded against the respective frames 32 and 42 when when *the device is folded into a chair struc ture. Thejback section 2 is provided with a frame'42 of strap'or' angle'bar and is made substantially identical withgthe frame 32 The'framez42 is also supplied withsuitable links 43 and springs 44 to hold the links under tension but allow yielding action; The

."frame 42 is provided with extensions 45 pivotally connected to the frame-14, whereby the parts' may be arranged'in the position 'shown in Figure 8 or swung upwardly to the positionshown Figure '9. A pair of legs 46 are pivotally connected with the frame 42 and are rigidly secured together near the outer ends by connecting brace47. A link 48 is pivotally connected with each of of the legs 46 and with suitable brackets 49 carried byv two of the legs 15. The parts are so proportioned that when'the "frame 42 is raised to. its'highest position, the legs 46 will swing past dead center, as shown in Figure 9, whereby the free end of the legs 46 rest againstthe links43 or, if desired, against somestop carried by frame 42. V7 here it is desired to'swing the back downwardly a short distance fromthe position shown in Figure 9, this may be readily done by first swinging the leg' 46 -o utwardly and then frame '42- downwardly the desired distance. After having swung the back downwardly a desired distance, the catches 50an'd 51 are swung "'into'*- operative. catches .are pivotally mounted on "the' seat 'section13 and are provided with aseries of books 52, saidhooks being adapted to interlock withtherespective pins 53 according to the angle at which -the' -back'has been positioned. In order to swingably connect the seat section 13 withthe body 12, sp'ecially constructed hinge members54 andf 55' are provided.- Itwill'be noted that these hinge members are substantiallyidenticalwith the exception that the hinge member 54 is provided with a shoulder '56-'whieh limits the swinging movement'of'the hinge members in one dlrection. Each of these hinge'members is provided with aside plate 57 adapted to be rivetedin place with a depending member 58 adapted to be riveted in placeand with a supporting flange 59. The flanges 59 on the 13 and 14respectively, as shown in Figure 4,

noted that the hinge member '54 is riveted to dotted position shown in.Figurel8, the frame 32 will be spaeed -a-bove frame14, i Suitable supporting feet 63 are carried by the frame 32 to support the rearpart of the seat section on the frame 14. By reason of this structure the weight ofthe person .using the chair, as

shownin Figurel, will be carried by the links ,33 and-not by the springs 25. If desired,

the mattress or .partof. the mattress may be arranged inthejspace between the body 12 and the seat section 13, as shown in Figure 9.

When thepartsjare in theposition shown in 5 Figure '1 twin 'theidotted positionijsho'wn :in Figure '8 and it should be 'desiredtounfold the device, it is only necessary to removethe cover 1, disengage catches 5(land 51 and then swing the sections 8 and 13 t0 file l w position. These i.

respective hinge members rest on the frames 0s while'a suitable pinf 60 connects the extenl'sions 61 and'62. From Figure 2 it will be the body 12, while the'hinge member 55' is riveted tdparts of the seat section 13. When the seatseetionisswu'ng over, for instance, to the position shown in Figure 9' or the position. The end pieces 'and 11 arethen;

raised and the vmattress adjusted until the parts assume the position shown in Figure 2. The device may be refolded into a chair by reverse movement. It will thus be seen that the device may be quickly and easily adj usted' from one formation to another. After the seat portion has been swung to the dotted sition. hen raised to a horizontal position spring-pressed pins 64 interlock with the catches for holding them temporarily in this raised position. As indicated in Figure2, a spring-pressed pin 64 is mountedin each of the blocks 65 and 66 so that both of the catches are properly taken care of. As indicated in Figure 13, the respective pins 64 snap into the respective apertures 67 and the catches 50 and 51. After the back has been swung upto the position shown in the dotted lines in Figure 8 the respective catches 50 and 5l are merely positioned downwardly until they interlock with the respective pins 53. In

this way one person may manipulate these parts In Figure 11 it will be noted that the hinge member 54 is provided with an offset portion 56. This is desirable in order that member 62' may overlap'member 61 and yet permit the frames 12 and 42 to remain V in alignment as shown in Figure 4:.
